    • Apparatus and techniques for performing JTAG testing on production devices and systems through industry standard interfaces. The devices employ processors configured to receive packetized test input data from a tester over a standard communication interface such as a USB or Ethernet port and perform associated testing operations defined by the test input data, such as JTAG-compliant testing. This is facilitated, in part, via use of a bridge and one or more DFx handlers, with the bridge operating as an interface between the DFx handlers and a bus and/or interconnect over which test input and result data is transferred via the standard communication interface. The techniques enable testing such as JTAG testing to be performed on fully-assembled devices and systems without requiring the use of dedicated test or debug ports.

    • A tamper resistant security seal is a laminated tape having a transparent carrier layer (2); an optical, diffraction pattern defining layer (3,4); and an adhesive layer (6) for adhering the tape to a substrate. The optical pattern, such as a hologram, defined by the optical pattern defining layer is visible from outside the laminate. The optical diffraction pattern defining layer (3) is formed by a polymeric layer permanently bonded to the transparent carrier layer which, when heated, causes the diffraction pattern to undergo an irreversible change. The adhesive is a pressure sensitive adhesive. An additional removable support layer may be provided on the carrier. The laminate is constructed so that a reduction in temperature below 0.degree. C. will cause an irreversible change in the diffraction pattern, or is such that subsequent to such a temperature reduction, attempted removal of the tape from a substrate will cause an irreversible change in the diffraction pattern.
